Hi @xiaoyun94, could you please provide more information about what appears to be stuck for you? We tried to reproduce this using the scripts you provided (on Ubuntu 20.04 and WSL), but we're not seeing any obvious problems. Generating the project and loading the project outline seemed to respond in a reasonable amount of time.

It must be the same as in #970.
Basically, it takes too long or too much resources to parse the compile_commands.json file and (for me, the cmaketool crashes).

[xiaoyun94]

the log records the memory problem actually, i have solved the problem by restarting vscode after modifying bash_profile NODE_OPTIONS=--max-old-space-size=8192.
I hope to adding a custom config weather omiting read compile_commands.json
#2609
